Title: Speed controller
Inventor: YANO HIROHISA
IPC: H02P29/00
Filed: 1989-09-08
Abstract: PURPOSE:To eliminate the necessity for adjusting a servo control device and to facilitate switching and changing a characteristic curve by providing a means for digitally converting the displacement amount of a slider, means for storing plural quantities of output characteristic curves for the displacement amount and a means for enabling a desired characteristic curve to be selected out of the above-mentioned characteristic curves. CONSTITUTION:Plural displacement and output characteristic curve data, assigned by a selecting circuit 6 with the digital displacement amount of a slider 2a serving as an address, are stored in a ROM5. A CPU4 reads the displacement amount of the slider 2a as a digital value from an A/D converter while it reads displacement amount and output characteristic curves, assigned by a user, also from the selecting circuit 6. Address data, determined by both the slider 2a and the selecting circuit 6, are input as a speed command to a D/A converter 7 to perform a fine control of a servo motor M.

Title: Radio network
Inventor: MIZUNO SEIICHI
IPC: H04W40/22
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To provide a radio network for changing an area where communication is possible without increasing base stations in accordance with the movement of a terminal machine. SOLUTION: A route generation packet where information showing oneself is filled is transmitted to all terminal machines 2 from a base station 1. The terminal machine 2 receiving the packet adds information showing oneself to the packet and transmits it to all the other terminal machines 2. The terminal machine 2 receiving the route generation packet transmits a response packet to a transmission source. The processing is periodically executed and the route of repeated communication between the base station 1 and the respective terminal machines 2 is detected. When the terminal machines 2 cannot directly make mutual communication, data is relayed and transmitted from the transmission source machine to the base station 1 and from the base station 1 to the transmission destination machine in accordance with the detected route.

Title: Surge absorber
Inventor: MOGI YUKIO
IPC: H01T4/12
Filed: 1999-08-20
Abstract: PROBLEM TO BE SOLVED: To obtain the stable surge absorbability of a long service life by using a comparatively inexpensive material with a simple manufacturing process by accommodating a pair of electrodes in an air-tightly sealed insulating housing, mounting a bulk glass body (core) between the electrodes, and having a pair of lead terminals taken out of the electrodes to the external of the insulating housing. SOLUTION: A bulk glass body is preferably manufactured by cutting a glass plate by a cutter and grinding both end surfaces thereof. When the excess voltage surge reached between lead terminals 13A, B, the discharging is generated along a side surface of a core 15 between electrodes 12A, B, and absorbs the surge. After the discharging, a side surface of the core 15 recovers an original normal condition, and keeps high insulating characteristic to the normal voltage. the discharging voltage is determined on the basis of a dimension of a gap between the electrodes or the like, and the stable discharging voltage can be obtained by improving the accuracy in size of the core 15. As the original condition is recovered after the discharging, long life of the surge absorber can be kept.

Title: Semiconductor laser
Inventor: HINO ISAO
IPC: H01S5/00
Filed: 1990-09-05
Abstract: PURPOSE:To make it possible to obtain a high reliability and high performance semiconductor laser by emitting protons or specific charged particles until they reach or penetrate an active layer from the surface of multilayer structure only near the end face which is a reflected plane of light or an emitting plane. CONSTITUTION:A clad layer 2, an active layer 3, a clad layer 3, and a cap layer 9 are arranged to grow successively on a n type GaAs substrate 1 based on a MOVEP process. Protons or charged particles with a mass number of 10 or below are emitted up to a depth where they penetrate the active layer 3 only near end face 8, thereby forming a proton emitting region 5. This makes it possible to inhibit the generation of optical absorption near the end face (window section) and prevent optical damage or end face deterioration. Moreover, since the window section allows the active layer 3 and each layer on the upper part of the active layer to serve as a high resistor, electric current is concentrated in a region which yields a laser gain efficiently even if no attempt is made to provide a special current limitation mechanism. This construction makes it possible to obtain a high reliability and high output semiconductor laser easily.
